I like the idea of enchanting items, it brings diversity and end game content. It also makes these hats useful, but obviously this need changes.
For an example, this scroll should have a much higher drop rate from boxes, as we are limited in how much we can get per day. Would also be nice if we could get them by normal monsters, like at a 0.001% (1 each 10.000 monsters).
Remember this is all to get a chance, not guaranteed useful stats.
